email html

PHP 4.2.2

Is there a way to send current displayed page (html output) as a body of an
email message ?
I have a button at the end of this page to send it to the user. the content
of the page is different for each user viewing it.

tried
mail($address,
$subject,file_get_contents("http://someserver.com/success.php"));
but the file_get_contents() is for php 4.3 and up.

Thank : )
